Alexandria is the focal point of Greek culture on the Mediterranean and the nexus of Roman trade routes to the deserts, inner Africa, and the East. In the mid-second century, Alexandria becomes one of the leading intellectual centers of the Christian Church. Egyptian temples are closed in 392 A.D. by order of the Byzantine emperor. The last known hieroglyphic inscription, from Philae, dates to 394 A.D. Egypt’s dry climate, combined with the new custom of burying the dead in their clothes and wrapped in shawls and hangings, helps preserve an unusual number of textiles.
